Granted: 1905-10-12
Abstract: 27,100. Mavor & Coulson, and Mavor, H. A.. Dec. 12. Motors, gearing for.-The movable primary and secondary members of an induction motor are connected together mechanically by means of an adjustable belt or friction speed gear, so that the velocity ratio of the two movable elements may be varied. In starting the motor, after one of the elements has attained a suitable speed, the velocity ratio being a maximum, the speed of this element is reduced and that of the other element increased by reducing the velocity ratio,of the variable speedgear. One element a of the motor is connected by an open belt b with a pulley c fixed to an intermediate shaft d. The other element is connected by a crossed belt f with a pulley e upon another shaft d'. The two shafts d, d' are connected together by means of gearing G, which may be adjusted by varying the distance between the pairs of cone pulleys 1, 1 and 2, 2. One of the two shafts d, d' may be directly connected to the one movable element of the motor, and the other shaft connected to the other movable element through toothed gearing. A friction clutch may be introduced between the shaft d and the pulley c, in which case, in starting the motor, the two movable elements may be disconnected by means of the friction gear and, after one of the elements has attained its maximum speed, its speed may be reduced and the speed of the other element increased by first applying the friction gear and then reducing the ratio of the variable-speed gear G. As described in Specification No. 5926, A.D. 1904, the power may be taken from any point of the system.

Inventor: AUDIBERT LOUIS AUGUSTE
Filed: 1905-02-03
Granted: 1905-06-08
Abstract: 2187. Audibert, L. A. Feb. 3. Alarms, burglar and like.-In an alarm lock, a bomb is exploded and a bell rung, when a false key is used to withdraw the bolt or when force is used to open the door. The lock case contains the sliding striker K, which is kept in its operative position against the action of a spring by the stop O bearing against the guide P, and is placed in this position by the removable handle N, the aperture in the lock case being closed by a sliding door. The striker is released to ignite the fulminating powder in the capsule C and explode the bomb d, by means of a system of levers R, S, T, U, V, which, when operated, cause a partial rotation of the striker and allow the stop O to pass through the guide P. The end of the lever V projects into the keyhole and is operated by any key other than the true one, which is specially slotted to receive the end of the lever. The lever V moves the lever R, and this in turn moves the lever S which turns the striker. The lever U is pivoted to a projection X<1> on the pivoted lever X, and is carried forward with it when the bolt G is shot, so that its hooked end l, Fig. 9, is engaged by a slide Y in the staple, Fig. 14. Excessive pressure on the door causes the slide Y to release the lever U which actuates the lever T and rotates the striker K. As the striker shoots forward, it makes electrical connexion between the wires f, g and rings the alarm bell.

Title: Means for Releasing Horses and other Animals and for Leading them from a Stable.
Inventor: HIGGINS ELMER EBEN
Filed: 1905-03-30
Granted: 1905-05-25
Abstract: 6791. Higgins, E. E., and Lansing, J. W. March 30. Fire - escapes. - Relates to means for releasing animals in stables in case of fire. By a pull on the main lead line 32, the animals are released and led to the back of their stalls and then down to the door. Branch lines 33, running through guides 16, pass over guide-sheaves down to the tripping- links 15, which are connected by chains to the hitching- links 11. A pull on the lines 33 raises the rings 15 and lifts the plungers 10-with which they engage-away from the links 11. As the links 15 rise further, camlugs 13 push them out of the notches 14 so that the animals are free at the head. The tension on the ropes then swings the protecting-sheaves 35, which are mounted on trunnions at the top and bottom, to the side so that the ropes fall away from the wall 6, and the animals on further pulling are led towards the guides 16. The flexible member 44 tied to the rope 32 becomes taut in the other direction to that shown in Fig. 2 when the animals have been led to the back of the stalls, and it then acts to pull the slide 28 to the right and allow the ring 31 to fall. By this operation, the slides 21 are traversed and the fingers 20 withdrawn from the support of the pivoted arms 19, which fall away and release the rings 16. The animals are led towards the door 2 by a further pull on the rope.

Abstract: 10,779. Saunders, A. T. May 8. Balls for use in various games, and provided with cores containing the elastic fluids under pressure, are formed with an air-tight lining of a composition which is produced by mixing glycerine and gelatin in a heated water-jacketed vessel, and, after cooling to 130‹ F. and allowing all air bubbles to pass off. adding desiccated albumen to the mixture. The mixture is cooled, and allowed to evaporate until of the required consistency. A ball or the core of a ball is then made from the composition, preferably by enclosing a small quantity in a hollow metal mould 1, Fig. 1, formed in two segments which can be locked together. The mould is heated to a temperature not exceeding 130‹ F., and is tumbled in various directions so as to form a ball of 2, Fig. 3, of even composition, the tumbling being maintained until the ball has set. The ball may be moulded in two halves from the sheeted composition, and the halves united. The ball 2, Fig. 3, is enclosed in a cover 3, preferably formed in two parts of vulcanized rubber, and is then enclosed in a metal shell similar to the shell 1, Fig. 1, and heated so as to coagulate the albumen, so that the lining shall not subsequently become liquid when heated. This ball, shown in Fig. 3, is enclosed in a suitable cover so as to form a ball suitable for polo, golf, cricket, or baseball. In some cases, the core is first wound with thread or yarn, with or without the application of a cement, and the core may previously be treated with a thin layer of glue dissolved in vinegar to which has been added a little glycerine. The core 2 may be pierced by a needle and inflated, and a second winding applied, the winding being treated with cement, or otherwise, to alter the specific gravity, strength, resiliency, &c. The core is preferably again inflated before the cover is applied, the whole being heated to soften the gelatin composition, and the needle preferably being inserted in an oblique position. The ball may be covered with cement before the cover is applied. For tennis balls, a vulcanized rubber ball 4, Fig. 4, is supplied with heated gelatin composition introduced by means of a hollow needle 5, the composition being evenly distributed before being coagulated. The usual cloth cover is applied.
